Section 10 16-Bit Timer Pulse Unit (TPU)
Bits 4 and 3—Clock Edge 1 and 0 (CKEG1, CKEG0): These bits select the input clock edge.
When the input clock is counted using both edges, the input clock period is halved (e.g. φ/4 both
edges = φ/2 rising edge). If phase counting mode is used on channels 1, 2, 4, and 5, this setting is
ignored and the phase counting mode setting has priority.

Note: Internal clock edge selection is valid when the input clock is φ/4 or slower. This setting is
Bits 2 to 0—Time Prescaler 2 to 0 (TPSC2 to TPSC0): These bits select the TCNT counter
clock. The clock source can be selected independently for each channel. Table 10.4 shows the
clock sources that can be set for each channel.
